A SPRING RETURN electric actuator designed for load requirements up to 450”lbs. The actuator comes standard with two auxiliary switches (Form C),
an internal low power heater, a NEMA 4X environmental rating, and in 120/230VAC or 24VAC/DC supply voltages. The PA Series mechanical connections
utilize an ISO5211 mounting system, size F07 with an 8 point 17mm female drive. The PA Series is offered in two different control modes....On/Off (2
position control), or Proportional (modulating control). Application requirements will dictate whether to utilize a CW (clockwise spring return) or CCW
(counter-clockwise spring return) model.

Theory of Operation - 2 Position
While power is present, the actuator will respond to drive control signals depending on the model chosen. A two position unit will drive until it reaches the
full end of travel setting opposite the spring return direction. A motor brake unit is utilized to HOLD the actuator in position until commanded to move OR
a loss of supply voltage. If power is lost or removed at any time, the brake is released and the mechanical spring mechanism returns the actuator to it’s
normal (unloaded) position. Once the spring mechanism has been released, the actuator will not drive under power again until a) the unit has reached
it’s fail stop (unloaded) position, and b) power has been restored to the actuator.

The following procedure is to be followed for set-up, calibration, testing and use of the PA-CW...2 Series Spring Return
quarter-turn electric actuators. Each unit is shipped from the factory with initial calibration of mechanical stops, cams
and switches completed. However, these are general settings and serve as a starting point for proper calibration of the
actuator in its’ real-world application
1. The actuator is shipped from the
factory in its full CW position. Before
mounting the actuator, make sure it
is fully unloaded.

8 point drive shaft and the ISO 5211 F07

This actuator has been
factory calibrated
to

operate between 0 and
900. Most quarter-turn
products will not require
recalibration of these
settings.

2. For two position actuators (PA...2-S4), make the electrical connections as shown below. For operation only four
connections are needed. The balance of the connections are used for options and features. Terminals A-C are an aux
switch for the closed position (adjustable), and terminals D-F are an aux switch for the open position (adjustable).
3. Mount the actuator to the valve or damper to be actuated. Remember, the
actuator is shipped in the spring return (unloaded) position. When viewed from
ABOVE the actuator, the spring CW units spring closed in a CW direction. Make
sure your valve or damper are in their CORRECT FAIL position before mounting
the actuator to them.
4. Once the two components are bolted together, apply power to the actuator
(neutral on 1, hot on 3) to drive the actuator to the FULLY WOUND position.
Then remove power to allow the spring return system to drive the device back
to the fail position.
Warning: Make NO adjustments to this device until you have contacted
the factory (352-544-8436) for assistance. Damage to product as a result of
incorrect cam and/or mechanical adjustments will NOT be covered under
warranty!
5. If it is determined that the end-stop position is not correctly aligned, it will be
necessary to ADJUST the MECHANICAL END STOP. To do this, remove the
adjustment housing cover using a 6mm hex key. There will be an adjustment
nut and a lock nut inside the housing. Loosen the adjustment nut using a 33mm
hex wrench, and while holding the nut, use a 17mm open end wrench to turn
the STOP ASSEMBLY. (CW to move the end stop more towards the FULLY
WOUND direction, or CCW to move the end stop further AWAY from the FULLY
WOUND direction). Do NOT turn the stop more than 4 turns in either direction!
6. Tighten the 33mm locknut to secure the adjustment.
7. It will now be necessary to re-adjust the electrical travel cam to coincide
with the new mechanical stop adjustment made in the steps above. With NO
POWER APPLIED to the actuator, use a 2.5mm hex key to loosen the #2 (RED)
cam set screw. Once it is free, rotate the hex key to the RIGHT a few degrees
to reset the switch roller arm. Then snug the set screw up against the camshaft
(CW) until slight pressure is felt. Then SLOWLY rotate the hex key pushing the
cam to the LEFT until you hear the “click” on the bottom switch indicating that
correct adjustment has been achieved. Tighten the cam set screw.
FM08_PA CW XXX2 Ver B 102008
NOTE: Incorrectly adjusted cams will prevent the actuator from running under
power.
8. Apply power to terminals 1 & 3 to drive the actuator approximately 20 degrees
CCW. Remove power to let the spring return system drive back to the new end
adjustment. Check the setting and repeat from step 5 if necessary.
9. Again apply power to terminals 1 & 3 to drive the actuator to the FULLY
WOUND position. The actuator will stop and HOLD when it reaches it’s end of
travel. DO NOT attempt to adjust the CCW end of travel unless it is absolutely
necessary. This can ONLY be done with power applied. If you remove power,
the actuator will spring closed, making it impossible to make the adjustment.
If you move the cam too far to the LEFT, the motor will drive the gear train
into the spring stops. This will DAMAGE the spring system. USE EXTREME
CAUTION IF ADJUSTMENT IS NEEDED.

10. If the STOP point is incorrect, the #1 (GREEN) cam must be adjusted.
Use a 2.5mm hex key to loosen the cam set screw. SLOWLY rotate the hex
key pushing the cam to the LEFT to drive FURTHER CCW, or to the RIGHT
Do NOT rotate the GREEN cam more
than 3 degrees to the LEFT...Serious Damage to the
actuator will result if the motor is allowed to drive the
gear train into the mechanical stop!!
to drive LESS CCW.
11. Tighten the cam set screw.
12. The THIRD (GREEN) cam is the OPEN auxiliary switch adjustment.
Drive the actuator to its OPEN position. Then use a 2.5mm hex key to
free up the cam set screw. Once it is free, rotate the hex key to the LEFT
a few degrees to reset the switch roller arm. Then snug the set screw up
against the camshaft (CW) until slight pressure is felt. Then SLOWLY rotate the hex key to the RIGHT until you hear the “click” on the third switch.
Continue to rotate the cam between 3 and 5 degrees to the RIGHT to
make sure the auxiliary cam switch changes state before the actuator
reaches its end of travel electrically. Tighten the cam set screw.
NOTE, THIS ACTUATOR MUST HAVE THE EMT FITTINGS WATER TIGHT WITH
CONDUIT DRAINAGE INSTALLED AND POWER SUPPLIED TO UNIT TO KEEP
THE HEATER WARM AT THE TIME OF INSTALLATION . This unit should NOT
be stored outside unless it is powered up. When this unit is NOT powered up, it
should be stored in a clean, dry environment at all times.
Page 4 of 6 PA-CW...2 Series
FM08_PA CW XXX2 Ver B 102008
13. The fourth (RED) cam is the CLOSED auxiliary switch adjustment.
Spring return the actuator to its CLOSED position. Then use a 2.5mm
hex key to free up the cam set screw. Once it is free, rotate the hex key
to the RIGHT a few degrees to reset the switch roller arm. Then snug
the set screw up against the camshaft (CW) until slight pressure is felt.
Then SLOWLY rotate the hex key and cam to the LEFT until you hear
the “click” on the fourth switch. Continue to rotate the cam between 3 and
5 degrees to the LEFT to make sure the auxiliary cam switch changes
state before the actuator reaches its end of travel electrically. Tighten the
cam set screw.
Application Notes:
1. These actuators are designed to be used in either a horizontal or upright position.
Do NOT mount the actuator with the top below a horizontal position.
2. When installing conduit, use proper techniques for entry into the actuator. Use drip loops to prevent conduit condensate from entering the actuator.
3. Both NPT conduit ports MUST use proper equipment to protect the NEMA 4x integrity of the housing.
4. The internal heater is to be used in ALL applications.
5. Do NOT install the actuator outdoors or in humid environments unless it is powered up and the heater is functioning.
6. Use proper wire size to prevent actuator failure (see chart below for proper wire sizing).
7. Mechanical travel stops are factory calibrated for 90 degree operation. These stops are NOT designed to adjust mechanical rotation by more than
+/- 3 degrees.
